    My first post.
    I have a son who is 8 years old and type 1. He was diagnosed at 18 months.
    He's been wearing a Dexcom for a few years now.
    Lately, I've been noticing that the receiver is WAY off on its readings.
    By way off, I mean sometimes it's almost by 100 if not more.
    Just the other night, the dex alarm went off saying URGENT LOW. I checked his BG with his meter and it said he was at 98.
    The following morning it was alarming at HIGH, checked him again, and his meter said he was at 129.
    Each time I manually put in the reading the meter gives me.
    What is going on?
    Has anyone experienced this sort of misreading behavior?
    Any suggestions?

    Have you changed where he wears it? My daughter's reading are much more variable and prone to pressure lows when she wears it on her lower back, as opposed to on her arm.

    Since he's worn it for years, I assume you know not to calibrate when arrows show movement?
